Neurodivergent player seeking DM

Hi! Not sure how all this works exactly, so open to pointers!

I’m helping my 22 year old brother find a D&D group. He is on the autism spectrum (think mentality of a 15-17 year old) and completely new to the game. He does best with voice communication and has difficulty with reading and typing, so we are looking specifically for a Discord voice-based game.

He is very enthusiastic, tracks well, annd has a great memory. He really wants to learn, but needs a slower pace and a patient, supportive DM.

please let me know if your group might be open to something like this, or if you have space for a beginner like him! He's sweet as pie and freakin’ hilarious. 

Thank you so much for your time.
